MANUFACTURE OFKPAPER-BOARD.

SPECIFICATION forming part of Letters Patent No. 269,816, dated December 26, 1882,

Application filed August 13, 1873. Renewed October 24. i881. (Model.)

To all whom it may concern Be it known that I, SILAS H. HAMILTON, of Bushnell, in the county Of'McDonough, and iul the State Ot" Illinois, have invented certain new i; and useful Improvements in the Manufacture of Flooring, Weather-Boarding, 85o., from Paper; and I do herebyv declare that the following is afull,clear, and exact description thereof, reference being had to the accompanying 1o drawings, making a part of this specification,

in which- Figure l is a perspective view of one end of asti-ip of my improved tlooringorplain weatherboarding. Fig. 2 is an end elevation of the same as connected with other strips of like construction. Fig. 3 vis a perspective view of a sheet of drop weatherboarding constructed by my improved method, and Fig.4 is an end elevation of the same.

2o Letters of like name and kind refer to like parts in each ot' the figures.

The design of .my invention is to lessen the cost and to increase the durability of buildings by rendering practicable the employment ot' paper as a substitute for wood-for use as fiooring, sheathing, weather-boarding. dsc.; and to this end it consists, as a new article of manufacture, in a sheet of weather-board composed of separaiely-iormed sheets or layers ot' paper 3o secured together by an adhesive mixture and pressure, and corrugated transversely, so as to cause its surface to present the appearance of several strips of ordinary weather-board, substantially as and for the purpose hereinafter shown. .v

The nature of my invention is shown equally in each ofthe articles hereinafter described.

In the annexed drawings, A and A represent.

sheets oi'paper-board, which are Vformed of any 4o suitable material, and are made dense by subjecting each to aheavy pressure. Two or more of the sheets A are nowcoated upon their sides with an adhesive preparation, preferably composed Of forty-nine parts of glue and one and one-eighth part of bichromate of potash dissolved in water, are placed in contact, and are then subjected to heavy pressure between two rollers, by which means said sheets are caused to adhere together and to become practically 5o homogeneous.

For flooring and ceiling the edges of the i sheets A arewotfset, as seen in Figs. ljand 2, so as to form rabbets at such points, by which means opportunityis afforded for securing to- -gether the rabbeted edges oftwo or more strips,

as shown in Fig.

For Ordinary overlapping weatherboarding the rabbets may. if desired, be omitted, while for drop weather-boarding (seen in Figs. 3 and 4) a board is employed that has a width equal 6o to that of several ordinary weatherboards, which said board is passed longitudinally through rollers that give to it the form shown in Figs.3 and 4, each board beingthus caused to present theappearance of two or more drop weather-boards.

The edges of the drop weather-boards may be left plain and caused to overlap, or they may be rabbeted in the manner before described.

The articles thus described possess all the 7o rigidity, durability, and ability to resist abrasive wear that is found in any ofthe soft Woods, while they are not subject to the changes which are occasioned by atmospheric inlinences upon wood.

I am aware1 that it is not new vto corrugate rooting-boards composed of an Outer sheet of metal and an inner sheet Ofpa-per. The article thus produced is not affected by changes of temperature or by moisture, and when worked 8o up into doors,sash ,or other like articles is less liable to change than any material heretofore employed.

Having thus fully set forth the nature and merits of my invention, what I claim as new 1s- As a new article of manufacture, a sheet of weather-board composedot' separately-formed sheets or layers ot' paper secured together by an adhesive mixture and pressure, and corru- 9o gated transversely, so as to cause its surface to present the appearance Ot' several strips of ordinary weather-board, substantially as and for the purpose shown.

In testimony that 4I claim the foregoing I 95 have hereunto sot my hand this 12th day of t August, 1878.

SILAS H. HAMILTON.
